'Tis possible. I'm also considering using a cheap camera as a dmonstration projectile; saboted, of course. 'Twould make a very good demonstration of being able to launch fragile payloads without destroying them.

Would be cool.As projectile, it would need to be a high-speed cam which directly transmits its recording wireless to the outside. Normal cameras will just record a few faded frames and then black.

Adding a camera (or a see through glass ) in the chamber would also be awesome. You could see the flame propagation and when adding some lightweight particles in it, also flow.

Do you mean you want to launch it with out destroying it or do you mean you want to launch and land it without destroying it?
The last one would be somewhat harder to do unless you fire it up into the sky, with a parachute.

Till the day I'm dieing, I'll keep them spuddies flying, 'cause I can!

Hmm but dont you think that the opening time per frame will be too long for such high speed? I mean, stuff could probably get faded out because of the speed.
Realize that the camera travels about 15 meter per frame recorded...
Not even talking about possible rotation.
One of those 250 fps sport cameras would be better.

1) Two words: Shuttered video.
2) I don't need it to be perfect video in any way shape or form. If the observer can see that it worked, that's all I need as mostly I'd just be trying to prove that the gun didn't kill the electronics. In other words, it's not that I want video per se, it's that video provides proof of survivability.
3) Start bumping the fps and the cost shoots through the roof pretty quickly. Too, high speed cameras (in my experience) rely on onboard storage (ie, aren't typically wireless). If the storage media gets killed in the impact (or you can't find the projectile), you've got nothing.
4) Choosing the trajectory wisely should minimize this issue.
